LCD Panel Meter Kit

No Longer Available
A digital meter is a lot easier to read and much more precise than its analogue equivalent. Moreover, this panel meter is comparable to an analogue one because a regulated power supply is no longer needed ; in many cases, an ordinary 9V battery is sufficient. As a result of the compact meter construction, there will never be problems finding a place to install it. It can easily be combined with an adapter circuit or sensor
Dimensions: 50 x 72mm (PCB)
Power Supply: 8-15Vdc or 9V Battery
